Answer:
volume of cylinder is πr^2h
Step-by-step explanation:
π = 22/7 or 3.14
r = radius of base of cylinder
h = height of cylinder
The answer to the first question is $633.75=12.75h-42
The answer to the second one is 48
9514 1404 393
Answer:
about 0.31°
Step-by-step explanation:
First of all, solve for sin(2θ):
3000 = (1/32)(3000^2)sin(2θ)
32(3000)/3000^2 = sin(2θ)
4/375 = sin(2θ) . . . . . . . simplify
Now, we find the corresponding angle:
2θ = arcsin(4/375) ≈ 0.61117°
θ ≈ 0.30558° ≈ 0.31°
The angle of elevation must be about 0.31°.
Answer:
-10² = -100
Step-by-step explanation:
The error in the evaluation occurred when the negative base (which is -10) was squared altogether outside of the parenthesis. (-10²) still results in <u>-100</u>.
The only time that the result will produce a positive 100 is when you square -10 this way: (-10)² = 100 because the negative sign is included with the squaring of base through the parenthesis.
Hope this helps.
I believe that the correct answer is B
